To (t l/6 whoiit Ina/y concern.-

Be it known that I, PERLEY R. GLASS, a citizen of the United States,residing at Quincy, in the county of Norfolk and State of Massachusetts,have invented an Improvement in Machines for Inserting Lacing-Studs, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like characters on the drawingsrepresenting like parts.

This invention has for its object to provide a lacing-hook-settingmachine of the class described in United States Patents Nos. 244,738 and277,985, dated, respectively, July 7, 1.881, and May 22, 1883, withnovel means for sustaining the lacing-hook while being set in the stock,said means including a, loosely sustained by hook-sustaining plate andguided by the head or upper end of a slotted plunger, means beingprovided for automatically moving said plate substantially at rightangles to the longitudinal axis of said plunger after said hook has beenset in the stock to thereby withdraw said plate from the throat of saidlacing-hook.

The hooks to be set by the apparatus to be herein described will besupplied singly to the hook-sustaining plate from a raceway common tosaid patents; but instead of the throat of the hook embracing a fixedlip at the upper end of the plunger, from which lip the throat of thehook has to be removed by a workman after the shank of the hook has beenset in the stock, the stock with the set hook being moved by the workmanhorizontally in a direction opposite the direction of movement of" thehook when coming on the saidiixed lip, I have provided a sliding framewith a plunger having at one end an ei'ilarged head that receives andguides said hook-sustaining plate in its movements as stated, said platewhen in its normal or hoolvreceiving position receiving upon it from theraceway the throat of the hook to be set and. sustaining said hook whilethe latter is being set in the stock, said plate positioning the shankof the hook accurately with relation to the shank-clenching surface,which may be 00111111011 to said patents, said hook-sustaining plate,after the hook has been set in the stock, being moved automaticallytransversely with relation to l the longitudinal axis of the plunger towith- I draw the hook-sustaining plate from the throat oi" the set hookwithout any tendency whatever oi" the plate to stick in the throat ofthe hook or spring the top of the hook, as would be the case if thehook-sustainer were moved. in the arc oi a circle when being withdrawnfrom the throat of the hook.

The part of the plunger having the head and serving as a guide for andcarrying the hook-sustaining plate is made adjustable in the slidingframe employed to reciprocate the plunger, so that when the plungerarrives in its lowered position the end of the hook sustaining plate maybe located accurately at the end 01'" the raceway that the hooks leavingthe raceway may pass therefrom and their throats embrace the end of saidplate then occupying its inward normal or hooksustaining position atright angles to the length of the raceway.

The plunger-head for taining plate is grooved, and the groove is made asa continuation of the groove in the raceway, so that the hook may passdirectly from the raceway-groove into the plungergroove and straddle thefree end of the sustaining-plate.

H erein the upper side of the hook-sustaining plate is located a littlebelow the upper end of the head of the plunger in which the plate isguided, such provision being of? advantage ''or the reason that itbecomes possible to reduce the friction of the plate against the stock,and consequently the plate may be slid in the head and be withdrawn fromthe set hook while the higher side walls of the upper end oi the plungercontact with the stock.

Figure 1,, in left-hand side elevation, represents a suil'icientportionof a hook-setting machine embodying my invention in one of thebest Forms now known to me. Fig. 2 is a right-hand view 01 Fig. 1 withthe box shown in said iligure at the right removed, together with theparts sustained thereby, the cam for moving the actuating-lever for thehooksustaining plate being shown by dotted lines. Fig. 3 shows in planview the upper side of the plunger and hook-sustaining plate slidablycarried thereby, together with part of the usual raceway extension forsupplying hooks to said plunger. Fig. 3 shows a top guiding thehook-sus- ICO view of the hook-sustaining plate detached. Fig. 4 is aside elevation of the plunger and hook-sustaining plate, the latterengaging the hook, the upper end of the plunger being partially brokenout and the plate being shown in longitudinal section. Fig. 5 is asimilar view with the stock encircling the shank of the hook, and Fig. 6is a similar view showing the tubular shank of the hook upset in thestock.

The tubular arm A will be supposed 'to be extended forwardly from asuitable framework, which may be such as shown in United States PatentNo. 277,985, which also has an overhanging arm forming part of saidframe that serves to sustain a bar, to the lower end of which isconnected the member m or top set of the hook-setting means, the samebeing provided with a central depending projection m to enter thetubular shank of the lacinghook as the latter is being upset in thestock by contact with the member m. The frame work of whatever shapewill have suitable bearings to sustain a shaft B, that may be rotated inany usual manner, said shaft having a cam B and a cam E, the latterhaving a lump f, to be described. A machine embodying my invention willbe provided with usual plates 0, (shown only in Fig. 3,) forming part ofthe lower end of a stud-guiding raceway or extension presenting ahook-guiding slot 6 such, for instance, as fully described in saidPatent N 0. 277,985 and designated therein in the same manner.

have provided the arm A with hubs a and a forming bearings for the rodsa a ex tended oppositely from a yoke a, said bars and yoke forming asliding frame adapted to be reciprocated vertically by or from the cam Bon shaft B. The rod a is hollow and receives the shank of the plunger(1, having at its upper end an enlarged head a. The plunger hasscrew-threads upon which are applied adjusting-nuts d, (see Figs. 1 and2,) change of position of which nuts on said screw-threads enables thehook-sustaining plate to be adjusted in the slide-frame that thehook-receiving end may be accurately located at exactly the properposition with relation to the end of the raceway and the groove 6therein, from which thelacing-hooks pass on their way to embrace theedge of the hook-sustaining plate, the groove in the upper end of theplunger and in the raceway at such times coinciding. The shank of theplunger is held in adjusted position in the hollow rod c by means of asmall screw (1. (Shown in Fig. 1.) The head a of the plunger is bored toreceive a retainer a (shown as a rod,) the upper end of which is cuppedto embrace the head 4 of the lacing-hook to be set. The retainer restson a spring a", and a screw (1 inserted through a hole in the head,enters a notch in the side of the retainer and prevents the latter frombeing projected too far. The retainer c acts frictionally to prevent thehook escaping from the end of the hook-sustaining plate as the latter iselevated by the plunger to set a hook in stock.

The upper end or head of the plunger is recessed to receive the head ofthe lacing-hook to be set as'the hook leaves the groove of the raceway,and said recess is shown wider than the space e between theraceway-plates e, the width of the recess being slightly in excess ofthe width of the head of the lacinghook, as shown best in Fig. 3.

The upper end of the plunger carries the hook-sustaining plate 0, whichis slidably connected with and guided by said plunger, so that it standsnormally in hookreceiving position, said plate having coacting with itmeans to be described to move the same transversely or at right anglesto the longitudinal axis of the plunger after a hook has been set towithdraw the plate from the set hook, as will be described, the saidhooks being set by a movement of the plunger and plate toward theclenching member to be described. As herein represented, the side wallsof the recess in the upper end of the plunger are grooved, as shown bydotted lines, Fig. 3, to receive and direct the side edges of thehook-sustaining plate as the latter is moved transversely of theplunger, as described, and, as best shown in Figs. 1 and 2, the upperside of the hook-sustaining plate is located below the upper end of thehead a, which enables the plate to be withdrawn from the throat of a sethook with less friction on the stock than would be the case if the topof the plate were flush with or occupied a position above the upper endof the head of the plunger. The end of the sustaining-plate is notched,as shown in Fig. 3 to receive the neck3 of the lacingstud, as shown inFig. 4. The plate 0 has a depending leg 0, from which extends an ear 0provided with a stud c Said leg also has e 'tended from it a stud c,that enters a suitable hole in the head (1 of the plunger and guides thehooksustaining plate in its transverse movements thereover or at rightangles to the longitudinal axis of the plunger. The recessed portion aof the upper part of the plunger a also serves to guide the plate 0 inits sliding movement at right angles to the axis of the plunger.

The front end of the arm A has attached thereto, as by bolts A in ears Athe box A, having concavities at its inner side to fit the rods c and cand form bearings for the same as the slide-frame carrying the plungeris reciprocated. The box A is provided with a stand A, upon which ispivoted at A a hookplate-moving device (shown as a lever A) that isloosely connected with the hook-sustaining plate by the slotted upperend of said lever embracing the stud 0 The lower end of the lever A hasa plug D, controlled as to IIO its position by a suitable set-nut D, theinner end of said plug meeting and being acted upon by a spring Dsustained in a suitable pocket and abutting said plug at its oppositeend. The spring D acts normally on said plug to turn the lever A in suchdirection as to retain the hook-sustaining plate 0 in the position shownin Figs. 1., 3, 4:, and 5, that the throat of the lacing-hook as thelatter leaves the groove 6 may immediately embrace and take seat on theend of said sustaining-plate, the latter, under control of the lever Aand spring D being held in suchposition as to present the shank of thehook carried by said plate in line with the depending central portion mof the top set m. The lever A is turned to move the guidedhook-sustaining plate at the end of the plunger to place the same in itsnormal or hook-receiving position and to withdraw the plate from thethroat of the hook after the latter has been set in the stock by orthrough the lump f of cam E on a roller f of a rodf lifting said. rod tomeet a projection. 6 of said lever andv turning the upper end thereofoutwardly against the stress of the spring D The sustaining-plate shownis withdrawn positively from the throat of the hook while the plungeroccupies its elevated position and immediately after the tubular shankof the hook has been upset in the stock by raising the plunger. Thestock is preferably provided with holes which are applied one after theother by the operator holding the stock in his hand over the point m ofthe upper set m, it having a clenching-shoulder surrounding the point m.

The thickness of the hook-sustaining plate is a little less than thespace between the under side of the head of the hook and that portionthereof from which the hollow shank 5 extends, so that the plate entersand fills the throat of the hook, and it is essential for the successfuloperation of the hook-setting p arts that the sustaining-plate be sosustained and guided by the plunger that said plate may be moved orslid. at the end thereof transversely or substantially at right anglesto the longitudinal axis of the plunger when said plate is to bewithdrawn from the throat of the set hook, for thereby all tendency ofthe plate to stick and bind in the throat of the hook is obviated andthe plate has no tendency whatever to pry up the head of the stud fromthat portion thereof which is set in the stock, and so enl: rge thethroat.

Fig. 6 shows the hook-sustaining plate retracted, as it will beimmediately after the shank of the hook has been set in the stock.

From the foregoing description it will be understood that the spring Dacts normally to move the hook-sustaining plate trans versely of thelongitudinal axis of the plunger A into its normal or hook-receivingposition, as represented. in Fig. 3, placing the receiving end of saidplate in such relation to the end of the groove 6 of the raceway thatthe throat of each lacing-hook as it leaves said groove will straddleimmed iately the end of the plate, the neck of the hook entering thenotch of the plate and theheadv of the .hook entering the recess at theupper end of the plunger. After a hook has been suppliedto thesustaining-pl ate the latter remains in its normal or hook-receivingposition with relation to the plunger while the plunger is raised thatthe top set may enter and expand or upset the shank of the hook. Whenthe hook has been set in the stock, the cam E acts through the .rod toturn the lever A and slide the hook-sustaining plate transversely or atright angles to the longitudinal axis of the plunger, thus withdrawingsaid plate from the throat of the hook which has been set in the stock,and immediately thereafter the plunger descends, the head of the hookescaping through the wider recess in the top of the plunger, said recessbeing wide enough to permit the escape of the hook set in the stock by arelatively vertical movement of the plunger rather than by a horizontalmovement of the hook and stock with relation to thelongitudinal axis ofthe plunger.

Prior to my invention I am not aware that the plunger of a machne forsetting lacing hooks has ever been provided with a guided.hook-sustaining plate slidable automatically transversely or at rightangles to the longitudinal axis of the plunger to thereby withdraw saidplate from the throat of the set hook without bendii'ig the headthereof, thus releasing the hook preparatory to the descent of theplunger to take a new hook, and consequentlyl do not intend to limit myinvention to the exact shape shown for said hook-sustaining plate nor tothe exact means shown for sustaining, guiding, or sliding the sametransversely of the longitudinal axis of the plunger to thus free theset hook.
